This is for a mostly street driven car. I'm putting together a MP 360 short block (p4876908) assembly. It has out of the box edelbrock heads and air gap intake, and comp cams xe274h with roller rockers. CR should be around 10.5. This is for my '67 Dart with A/T and 3.23 gears. I have not yet purchased a torque converter, but want the thing streetable. I was thinking around 2200 stall. Any suggestions? I was leaning toward the Edelbrock Thunder AVS 800cfm.

I really don't want to change the gears right now. I have two complete center sections and they're both 3.23. Some day I might set one up different for track time, but I have a lot of other problems to throw money at right now.

what kind of compression will you end up with? 323's should be fine, I'd up the converter to something like a 2600-2800 stall. for a "cheap" converter that's pretty good, I'd look at the MP 175K.

I'd lean towards the 800 eddie, or a themoquad built by demonsizzler

I started this build about 5 years ago. IIRC the compression was just under 10.5. I was following something close to what was done in I believe a Hot Rod magazine article. They ended up with just over 400hp and 400ft/lb torque. Five years and 2 houses later I can't find the article.

Comp cams site calls for a 2200+ stall converter for that cam and says the rpm range is from 1800 to 6000. That's why I was going to go with a 2200 stall.

Also forgot to mention I have a '66 19 spline 727 built already. That limits me on converter choices. I have been considering keeping the 904 that is in the car.

Holley 750 carb. With those gears I would suggest a vacuum carb over a dp but either can be made to work with some tuning(be prepared to buy a tuning kit).

Yeah but you're a bit under geared for that cam, which is why a higher stall would be better. I agree something around the 2600-2800 mark would be best.

You can order TQ's in any spline configuration!!

Or change your imput shaft? 904's are fine???

I guess I'm going to disagree with the carb of choice so far. The OP says this is a 360 that is a street only car. There's no reason to overcarb a street car. It will run way better with better throttle response and better mpg with a slightly smaller carb. Math says a 366 cube motor at 6500 RPM and 95% V.E. can use 654 CFM. Most motors will never see close to 95% V.E. And a double pumper on a street car with 3.23 or 3.55 gears is just plain bad advice. My choice would be a Holley 670 Street Avenger series.

The Edelbrock carb should work just fine for your application. They are easy to tune and work pretty well on those types of motors. A one inch insulator under the carb helps a bunch with any hot soak problem.

Wrong 3310 vacuum secondary and edelbrock carbs till the air door or secondaries receive enough vacuum created at the top of the venturies to open are 2 barrels!! 3310 is the best all round carb made.

3310. Also very tuneable, w/vac spring asst. for secondaries and quick change top.

Uh, you are correct,.... but this also applies to every vacuum secondary carb Holley has ever made. Not just the 3310. I'll stand by my choice of the smaller 670cfm (Vacuum secondary) street avenger series. Neither is wrong, and both would work. My feeling is that the street avenger would offer crisper throttle response, as the venturies are slightly smaller and will offer a stronger vacuum signal.

PS. The secondary vacuum signal is recieved through the baseplate, not at the top of the venturies.

If you stick with the 3.23s & 2200 stall, i'd run the 3310, if you plan on changing to a higher stall (around 3000+) & more gear run the 4779 750dp.

Before jumping the gun & buying "new", keep checking on e-bay, i picked up this carb with 11 hrs. left.

Thanks for the help so far. I have 2 used carbs sitting around, but I think one is too small (Holley 4160 600cfm single feed) and the other is junk and a spread bore (Holley 4011 650cfm dual feed). I guess I should start with what CFM do you suggest? I would think less than a 750 would bee too small??? I have no problem with buying used and rebuilding one. Also car is set up for a manual choke and I think I would like to keep it that way.

750 would be the upper limit. IMO anything between 700 and up will be acceptable. That 650 spread bore carb would even do the job if you had a spreadbore intake.

Andy,

With the spacer and the air gap intake, what throttle linkage will I need?

I would use the 4160 600cfm that you have.
Using any carb bigger than a 650 would be
over kill. bigger isn't better
I run a 650 mighty demon on my built 360.
ported x heads, airgap, solid cam.
runs 8.0 1/8th mile.

Run the 750 or 800 AVS or AFB. Get the jets dialed in properly and you will get much better gas mileage than a Holley especially on the street...It is all that motor can use..especially given the 323's....Chrysler ran the small one on the 68-70 340's and that was a great set up...The hot ticket on a 383 was to take the 440 750 AVS and gain 10hp or so....

I run a stinkin 1971 750 avs on my 71 street 440 cuda with cast iron intake and I run 11.89 with it at 113mph....
They are the easiest carb to work on in my opinion...not as many gaskets to leak as on a Holley and the floats are a measured setting...So you are not getting gasoline all over your new motor adjusting the floats on the Holleys...

The new AFB's and AVs's are jetted on the extremely fat side...You will most likely need to reduce them down.....and keep them 4 corner square of the same size. Good Luck.

Just the basic small block kit and return. Part number is AR004 and AR027. You need to run a cable kickdown with that setup. Swing by my shop and I'll set you up with the parts.
